Perform a chkdsk on the drive using a Windows PC to help troubleshoot your issue.

  1. Connect the drive to your PC
  2. Search in windows for cmd then press enter.
  3. In the command prompt, type chkdsk x: but replace x with the letter for your drive.
  4. Screenshot the output.

We are looking to verify the following:

  1. No issues are found.
  2. If Windows finds problems, close and reopen the command prompt
  3. Type chkdsk /f x: but replace x with the letter for your drive.
  4. When it asks to convert lost chains to files, type n
  5. You have 32kb (32768 bytes) in each allocation unit.
  • If you have a different allocation unit size backup your data and reformat to FAT32 with the correct allocation unit size.
